Torin Swivel Weld-On Trailer Jack 2,000 lb Capacity — 3"–4" Pipe Mount, 10.5"–20.5" Lift, Zinc Finish

The Torin ATR39003B is a weld-on, swing-back trailer tongue jack that lifts up to 2,000 pounds and adjusts from 10½" to 20½" for 3"–4" tongues.

Built for trailers that need a sturdy, compact lifting solution, this Torin swivel jack secures to a pipe mount and swings back against the tongue when not in use. A zinc finish helps resist corrosion, and the wind handle offers quick, smooth cranking. It’s a simple mechanical option for positioning and stabilizing trailers up to one ton without electrical components.

How much weight can this trailer jack safely support?

The Torin ATR39003B is rated for a 2,000 lb (1 ton) static capacity, suitable for many utility, small equipment, and boat trailers. Capacity refers to vertical lifting load at the jack; always account for tongue weight and trailer configuration when choosing a jack.

• Maximum lift capacity: 2,000 pounds (1 ton)
• Designed for tongue loads, not entire trailer axle weight
• Recommended for light-to-medium trailers and equipment trailers

What are the height and mounting specifications?

This weld-on swivel jack adjusts in height from 10.5 inches to 20.5 inches, giving flexibility for coupler alignment and ground clearance. It accepts trailer tongues with 3" to 4" diameter pipe mounts and is intended to be welded permanently to the tongue tube.

• Height range: 10.5" to 20.5" for precise coupling
• Fits pipe mounts measuring 3"–4" in diameter
• Weld-on installation for a fixed, secure attachment

How does the swing-back and crank handle improve usability?

The swing-back design folds the jack against the trailer tongue when not in use, keeping it out of the way during towing. A wind-style handle lets you raise and lower the tongue smoothly and with minimal effort, providing controlled movement when hitching or leveling.

• Swing-back action tucks the jack behind the tongue for travel
• Wind handle offers consistent, low-effort cranking
• Durable mechanism for repeated hitching and storage cycles

What protection and warranty does the jack include?

The unit has a zinc coating to reduce corrosion from road salt and weather exposure, extending service life in outdoor environments. Torin includes a limited one-year manufacturer warranty covering defects in materials and workmanship under normal use.

• Zinc-painted finish for improved rust resistance
• Built for outdoor, trailer-mounted conditions
• Limited 1-year manufacturer warranty for peace of mind
